Question

consider a circular road of radius 20 meter banked at an angle of 15°with what speed the car has to move so that it will have a safe turn​

Answer 1

Answer :

Radius of circular path = 20m

Angle of banking = 15°

We have to find maximum safe speed of the car$.$

★ Banking of tracks (roads) : The maximum velocity with which a vehicle (in the absence of friction) can negotiate a circular road of radius r and baked at an angle θ is given by

• v²= rg tanθ

By substituting the given values,

➝ v² = 20 × 10 × tan15°

➝ v² = 200 × 0.27

➝ v = √54

➝ v = 7.35 m/s

• v = √(μ r g)
